Askåterföring i Jämtland : biobränslets och askans innehåll av tungmetaller relaterat till markernas geokemi

Using biofuels from regeneration cuttings is becoming more common in Sweden. Ash from the combustion of biofuels contains many valuable nutrients and base cations. The Swedish Forest Agency recommends that ash should be recycled to clearings where biofuels have been removed, to avoid future impoverishment of Swedish woodlands. In Jämtland, in northern Sweden, a large quantity of biofuels are taken out from cuttings but ash recycling has not yet been tried. The aim of this thesis was to examine the conditions for ash recycling in Jämtland regarding to soil chemistry and heavy metal content in soil and biofuels.

Elevers attityder, kunskaper och beteenden : inom kunskapsområdet konsumtion och ekonomi i Hem- och konsumentkunskap

SammanfattningKonsumtion och ekonomi är områden som på olika sätt påverkar människors liv. Forskning visar att värderingar, identiteter och idéer grundas på konsumtion. Syftet med denna studie var att undersöka elevernas attityder, kunskaper och beteenden inom konsumtion och ekonomi som är ett kunskapsområde inom ämnet hem- och konsumentkunskap. Författaren var även intresserad av att undersöka om det fanns skillnader mellan två skolor bland elever i årskurs nio som skiljer sig åt vad gäller upptagningsområde och skolans geografiska läge. 153 enkäter delades ut och resultatet analyserades med dataprogrammet IBM Statistics Version 20 (SPSS 2010).

Fosforprocesser i Bornsjön, Stockholms reservvattentäkt - dynamisk massbalansmodellering med LakeMab

Bornsjön är Stockholms viktigaste reservvattentäkt och kan tillgodose staden med dricksvatten i flera månader om Mälaren skulle slås ut. Det är därför viktigt att Bornsjön håller en god vattenkvalitet. Under de senaste åren har vattenkvaliteten avseende totalfosfor i Bornsjön försämrats. Hög belastning av fosfor kan leda till övergödning i en sjö. När en sjö är övergödd uppstår ökad syreförbrukning som kan leda till syrebrist.

Landskapsideal : hur uppväxtens landskap formar individen

The landscape can be something that you rest your eyes on, something that goes quickly past outside the windscreen or the place for the daily work. To me, landscape is everything around us ? the city, the field and the forest. But what is landscape for you? What does the idea of the landscape stand for? How does our view of the landscape become influenced of the place where we grow up? And the differences between peoples different views of the landscape ? what does they depend on? My point of the view for this paper is that the landscape ideals mostly depend on the landscape where you grow up and that it depends less on the differences between the individuals. As a landscape architect the idea of the landscape is the essential. The more we learn, the more we realize how complex it is, but deep down we always have our own experiences and memories and that shapes our personalities.

Näsbyholm - parken och de närmaste omgivningarna ur ett historiskt och nutida perspektiv

The goal of this work has been to search historical materials, to identify the park's historical development, to prepare proposals on measures and that work should be the basis for further research. The aim has been to train us in searching for and use of materials and to gain an understanding of the process of work with older plants. In the process we have sought and found materials in archives, through literary and oral sources, and email contacts. Because of its excellent location perched on an islet in the low landscape Näsbyholm was long a fortress. The old castle on Näsbyholm was from the late 1400s but the site was fortified much earlier. The islet was at this time completely surrounded by water and there was a drawbridge over the narrow waterline. The owners are liable since the late 1200s.

Planering av lägerområden : exemplet Sjöröd

This is a final thesis on the landscape architecture program at the Swedish University of Agricultural Sciences. It is the end of five years of studies and comprises 30 ECTS. This thesis is about the camp area Sjöröd, located by Gyllebosjön (the Gyllebo Lake) on Österlen in Skåne, southern Sweden. The thesis results in plan for how the area could be used in the future. It also raises the questions; what scouting of today is, how it is to be developed for the future, what a camp is and which aims the scout movement has set up for itself and its activities. The thesis also treats what is typical for Skåne, for Österlen and for the area around Sjöröd as a starting point.

Challenges and incentives for sustainable manure management in Russia

The Baltic Sea is threatened by eutrophication that largely is due to nutrient leaching from farmland within the catchment area. To solve this problem the surrounding countries cooperate within various configurations such as HELCOM and the EU-financed project Baltic Compass. Poor manure management in Russia has been discussed frequently the last couple of years. A literature review of different types of reports and legal acts is the core of this degree project which has been performed in connection to two ongoing research projects financed by EU (Baltic Compass) and SIDA. It is supplemented with interviews with Swedish agricultural consultants and travel reports from two occasions when I had the opportunity to discuss with Russians active within the agricultural sector. Different hypotheses were investigated and discussed. The environmental debate in Russia is quiet and there is a widespread approach that economic profit always trumps environmental concern ? a Soviet heritage that influence the Russian agriculture considerably. The Russian legal acts on stable manure management focus mainly on sanitary questions and only secondary on nutrient leaching.

Dagvattnets föroreningar som potentiellt hot för en god ekologisk och kemisk status i ytvattnet : En kartläggning av Vallentuna tätorts dagvattenhantering utifrån dess tillsynsbehov

The EU's Water Framework Directive aims to a long-term and sustainable use of our water resources and wants to ensure good water quality in Europe's water bodies. Discharge of polluted stormwater into receiving waters can be a threat to their ecological and chemical status. Municipalities are responsible for supervision of the environmental quality standards (EQS) and therefore need to gain knowledge of current stormwater management, the expected level of pollution emissions and possible appropriate purification steps to ensure that the goal of good water quality is achieved.This master thesis aims to provide this knowledge in the example case of Vallentunas urban area and wants to prepare future oversight so that it can be assessed how much the discharge of polluted stormwater into the local receiving water is a threat to its status. With the help of maps, aerial photographs, site observations and individual discussions those areas are mapped where appearance of moderate to highly polluted stormwater could be suspected. The degree of pollution at the discharge points is determined based on land use upstream and uses standard values according to the administrators assistance "Tillsyn av dagvatten" (MSL 2014).The study identifies 100 areas in need of supervision regarding their stormwater management.

Threats and opportunities for the survival of the Yangtze finless porpoise

The Yangtze finless porpoise (Neophocaena phocaenoides asiaorientalis), is a small freshwater cetacean which has recently fallen dramatically in number. It is an endemic species for the Yangtze River and unless drastic action is taken, it risks the same fate as the now functionally extinct Yangtze river dolphin (Lipotes vexillifer). Threats to the porpoise are diverse but they have in common that they are caused by man. Development of the river has been made to supply a growing human population with food, hydropower, and to reduce the risk of flooding. These changes have resulted in a degraded habitat for the porpoise.

Användning av lekplatser : en fallstudie i Vänersborgs kommun

The aim with this report is to investigate what influence the way playgrounds are used throw the case study in Vänersborg, and also to find methods for municipalities to collect information about how playgrounds are used. The methods were observations, interviews with parents and children, a questionary with questions about what playgrounds they used, how often and why they used them and what the children used to do there. There was also a demographic investigation and documentary research. The most popular playground, Skräcklan, gets visitors from all parts of the municipality. It is located in a park with a view over the lake Vänern, there is a parking place and a café and it has furthermore a large area and many play equipments. Many of the families make shorter trips and picnics to this place. In exception of this playground, the families almost always go to the playground in their neighborhood and their part of the town.

Utveckling i Ammerån : att skapa ett hållbart fiske med hög kvalitet

Ammerån which is a small forest river in eastern Jämtland is a well-known river that has been a popular fishing river for a long time. The actual Ammerån begins downstream the lake Solbergsvattnet at Hammerdal and flows into the Indalsälven 10 km upstream Hammarstrand. The river environment switches between forests with wilderness feeling and open agricultural land. The entire Ammerån is today a nature reserve and protected from hydropower development. Fishing in Ammerån has mainly been focused on trout and grayling, and is so even today.

Beräkning av massbalanser för metaller i vatten samt miljöriskbedömning av Nerån vid Österbyverken i Östhammars kommun

Österbyverken is an industrial estate in Östhammars municipality in Uppland, Sweden. Many different activities have taken place on the estate the last 600 years. During the last 15 years both health and environmental studies have been made by different companies. At the most recent study a great increase of metals in Nerån, a river that runs partly through and partly next to the estate, was identified with mass balances. The purpose of this thesis is to accomplish a deepened study about the reasons for the increase of metals in Nerån.

Vallbrott med hjälp av grisar :

To investigate the possibilities for effective soil tillage, that could imply lower costs, lower negative environmental impact and in addition a meaningful occupation for foraging pigs, a field experiment was carried out in Gränna, Småland, during growing season 2006. The experiment contained two treatments that were repeated three times and were carried out on a couch grass-infected fallow on a light soil close to Sweden?s second largest lake, Vättern. Ploughing was one treatment and pig rooting followed by ploughing, was the other. The experiment was conducted according to the guidelines of organic growing and seedbed preparation was done the same way in the two treatments. The pigs, three groups of five half-year old Linderödssvin (an old Swedish breed), was encouraged to perform an even tillage by strip-grazing, i.e.

Grundvattnets geokemi vid Gladhammars gruvfält, Västervik. Effekter av äldre tiders kobolt- och kopparbrytning

The municipality of Västervik, with support from Envipro Miljöteknik AB, is carrying out a main study of the minefields at Gladhammar. Mining of iron, copper and cobalt under different periods from the 16th century until the end of the 19th century has led to discharges of metals to the lakes situated downstream. The aim of the main study is to investigate the possibilities to reduce the environmental load on the surrounding ground and water caused by heavy metals from the mine. The present report is a part of the main study. The aim of the work is to investigate the geochemistry of the groundwater.
